The k+ ion has an electron structure that is identical to which inert gas?

You should understand the concept that ions occur because they want to achieve stability. Among the elements in the periodic table, only Group 8 or the noble gases are stable. Hence, other elements must gain or lose electrons so that they can achieve the same configuration of the nearest noble gas to them. For potassium, the nearest one is Argon.

What is the empirical formula of a compound that is 18.8% Li, 16.3% C , and 64.9% O

Greetings!

To find the empirical formula you need the relative atomic mass of each element!

Li = 6.9

C = 12

O = 16

You can simply change the percentages into full grams

Li = 18.8g

C = 16.3g

O = 64.9

Then you use this to find the Number of moles = amount in grams / atomic mass

Li = 18.8 ÷ 6.9 = 2.7246

C = 16.3 ÷ 12 = 1.3583

O = 64.9 ÷ 16 = 4.0562

Then divide each number of moles by the smallest value:

Li = 2.7246 ÷ 1.3583 = 2.0

C = 1.3583 ÷ 1.3583 = 1

O = 4.0562 ÷ 1.3583 = 2.9 ≈ 3

So that means that there are 2 Li, 1 C, and 3 O

Empirical formula would be:

Li₂CO₃

The rate of a certain reaction is given by the following rate law: rate Use this information to answer the question below. At a certain concentration of H2 and NH3, the initial rate of reaction is 4.0 x 105 M / s. What would the initial rate of the reaction be if the concentration of H2 were doubled

Initial rate of the reaction when concentration of hydrogen gas is doubled will be .

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

Initial rate of the reaction = R =

The initial rate of the reaction when concentration of hydrogen gas is doubled : R'

Initial rate of the reaction when concentration of hydrogen gas is doubled will be .

Select the correct chronological order for the discoveries by the following scientists a)Thompson. Dalton. Rutherford, Bohr
b)Dalton, Thompson, Rutherford, Bohr
c)Bohr, Rutherford, Dalton, Thompson
d)Rutherford, Dalton, Thompson, Bohr

The correct chronological order for the discoveries by the scientists are  Dalton, Thompson, Rutherford, Bohr. Therefore, option B is correct.

What are discoveries ?

The act of discovering something, whether it be data, a location, or an item, particularly when doing so for the first time: the discovery of electricity.

Leonardo was a prolific scientist. a travel or exploration voyage. An investigation into a murder was opened when a corpse was found in the brush.

While Discovery aids in identifying the adjustments and enhancements that are required, it also aids in streamlining and ranking those changes, helping you choose which requests are most crucial and how to accommodate everyone's requirements.

In order to make a discovery, one must present observational data and make an effort to form a preliminary knowledge of a phenomenon.

Thus, option B is correct.

What is the concentration of hydroxide ions in pure water at 30.0c, if kw at this temperature is 1.47 x 10-14?

In pure water, the concentration of hydronium ions, or H⁺, will equal the concentration of hydroxide ions. That is [H⁺] = [OH⁻].

Remember that Kw = [H⁺][OH⁻] for water and if [H⁺] and [OH⁻] are both equal, we can easily solve for them by taking the square root of Kw.

[H⁺] = [OH⁻] = sqrt(1.47*10^-14) = 1.21*10^-7

The concentration of hydroxide ions at 30 degrees Celsius is 1.21*10^-7

The evaporation of liquid water from the surface of the earth is an important step in the water cycle. How do water molecules obtain enough kinetic energy to escape into the gas state?

The sun heats up the molecules, which makes them move faster and faster. The molecules escape into gas when the kinetic energy of the molecule is higher than the force that keeps it together.

2NH4Cl(s)+Ba(OH)2⋅8H2O(s)→2NH3(aq)+BaCl2(aq)+10H2O(l) The ΔH for this reaction is 54.8 kJ . How much energy would be absorbed if 24.7 g of NH4Cl reacts?

1) Chemical equation

2NH4Cl(s)+Ba(OH)2⋅8H2O(s)→2NH3(aq)+BaCl2(aq)+10H2O(l)

2) Stoichiometric ratios

2 mol NH4Cl(s) : 54.8 KJ

3) Convert 24.7 g of NH4Cl into number of moles, using the molar mass

molar mass of NH4Cl = 14 g/mol + 4*1 g/mol + 35.5 g/mol = 53.5 g/mol

number of moles = mass in grams / molar mass

number of moles = 24.7 g / 53.5 g/mol = 0.462 moles

4) Use proportions:

2 moles NH4Cl / 54.8 kJ = 0.462 moles / x

=> x = 0.462 moles * 54.8 kJ / 2 moles = 12.7 kJ
